Logical Unit Number (LUN) and volume management

Nondisruptive LUN and volume creation and deletion are supported. When a LUN or volume is deleted, the capacity can be reformatted and reused.

LUNs and volumes can be configured to span arrays, therefore the size of the volume or LUN is not constrained by the size of the array. LUNs up to 16 TB are supported. CKD volumes up to 1 TB (1,182,006 cylinders) are supported.

Dynamic Volume Expansion supporting application data growth

The IBM System Storage DS8000 series supports Dynamic Volume Expansion, allowing the size of a logical volume to be increased while it is online to a host system. This capability can simplify management by enabling easier online volume expansion to support application data growth. The maximum volume size is limited to the currently supported maximum size for DS8000 :

Open Systems (Fixed Block - FB) volumes - 16 TB

System z® (CKD) volumes - 1 TB (1,182,006 cylinders)

Volumes that are expanded can be online during and after the execution of the function. Volumes may not be in copy services relationships (Point-in-Time Copy, FlashCopy® SE, Metro Mirror, Global Mirror, Metro/Global Mirror, and z/OS® Global Mirror functions) while expansion is taking place. The function can be managed and configured via the DS Storage Manager, DS CLI, and DS Open API. IBM System z and System p® servers support and recognize the expanded volumes within the DS8000 .

All other servers may require additional steps to be put into place in order to support and recognize the expanded volumes within the DS8000 . The Dynamic Volume Expansion capability is provided with the DS8000 series at no additional charge.

Up to 130,560 FICON® logical paths (1,280 logical paths per control unit image)

Up to 8,000 process logins (509 per SCSI-FCP port)

Simplified storage management for System z with z/OS

For System z and z/OS environments, DS8870 models can support 1 TB (1,182,006 cylinders) 3390 volumes. It can help relieve addressing constraints, improve disk resource utilization, and improve storage administrator productivity by providing the ability to consolidate multiple disk volumes into a single address.

Administration and management

Online configuration capability features a web-based GUI designed to offer increased ease of use

A single command line interface (CLI) supports both logical configuration and copy services

Capabilities such as remote code distribution and email notification of link failures can also improve availability

Choice of models and features

DS8870 has similar scalability as previous DS8000 and DS8800 systems. With a 2, 4, 8, or 16-core processor complex, the DS8870 Model 961 supports up to 240 2.5-inch disk drives for a maximum capacity of up to 216 TB. It also supports up to 1 TB of processor memory with up to 8 Fibre Channel/FICON adapters. With an optional expansion unit (DS8870 Model 96E), it scales as follows:

With one DS8870 Model 96E Expansion Unit, the DS8870 Model 961 (8 or 16-core) supports up to 576 disk drives, providing up to 518 TB of physical capacity with 900 GB SAS disk drives, up to 288 drives providing up to 864 TB of physical capacity with 3 TB nearline SAS disk drives, and up to 16 Fibre Channel/FICON adapters

With two DS8870 Model 96E Expansion Units, the DS8870 Model 961 (8 or 16-core) supports up to 1,056 disk drives, providing up to 950 TB of physical capacity with 900 GB SAS disk drives, up to 528 drives providing up to 1.6 PB of physical capacity with 3 TB nearline SAS disk drives, and up to 16 Fibre Channel/FICON adapters

With a third DS8870 Model 96E Expansion Unit, the DS8870 Model 961 (8-core with 256 GB cache or 16-core) supports up to 1,536 disk drives, providing up to 1.4 PB of physical capacity with 900 GB SAS disk drives, up to 768 drives providing up to 2.3 PB of physical capacity with 3 TB nearline SAS disk drives, and up to 16 Fibre Channel/FICON adapters

To meet performance and configuration needs, DS8870 Model 961 offers a 2, 4, 8, or 16-core processor complex. Refer to the following table for more detail on supported drive and adaptercounts with the two available configuration options.

Price, performance, and capacity flexibility to help address specific application and business requirements is provided through drive intermix support.

Physical capacity for the DS8000 series is purchased via disk drive sets. A disk drive set contains 16 identical disk drives with the same capacity and rpm. Disk drive sets are available in many types as shown in the following table. For additional flexibility, feature conversions are available to exchange existing disk drive sets when purchasing new disk drive sets with higher capacity.

IBM Standby CoD solutions are designed to address the changing storage needs of rapidly growing businesses. IBM Standby CoD for the DS8000 offering allows inactive disk drives to be installed and easily activated as business needs require.

Standby CoD provides the ability to tap into additional storage and is particularly attractive for rapid or unpredictable growth, or just for the knowledge that extra storage will be there when needed.

With this offering, up to six Standby CoD disk drive sets (96 disk drives) can be factory or field installed into the system. For activation, the disk drives should be logically configured. This is a nondisruptive activity that does not require intervention from IBM . Upon activation of any portion of a Standby CoD disk drive set, an order should be placed with IBM to initiate billing for the activated set. At that time, replacement Standby CoD disk drive sets may also be ordered.

This offering allows licensed functions to be purchased based upon the machine's physical capacity, excluding unconfigured Standby CoD capacity.

This offering does not have an offering fee premium. A Standby CoD disk drive set must be activated within a 12-month period from the date of installation and all activation is permanent. Contact your IBM representative to obtain additional information regarding Standby CoD offering terms and conditions.

Full disk encryption

IBM recognizes the requirement for data protection, not only from hardware or software failures, but also from physical relocation of hardware, theft, and retasking of existing hardware. Full disk encryption drive sets allow data encryption at rest on a DS8000 series storage controller, helping to mitigate the threat of theft, mismanagement, or loss of business critical data.

The DS8000 series allows encryption using any of the available drives with key management services supported by Tivoli® Key Lifecycle Manager software. Enabling encryption is optional, and may be activated using feature number 1750.

The full disk encryption support feature is available for plantand field orders. Field configured, nonencryption supporting systems will be allowed to activate encryption drives installed at an existing location. The entire subsystem must either be all encrypted by activating encryption with activation indicator feature number 1750 or all nonencrypted by ordering encryption deactivation indicator feature number 1754. The encrypted drive activation indicator feature number 1750 and the corresponding DS8000 series Function Authorization (2396-LFA feature number 1750) are available for ordering.

Additionally, an environment verification process must be completed to support best practice configuration of the encryption solution. This verification can be requested from IBM Lab Based Services (recommended), or completed by the customer, but is a prerequisite of the encryption solution activation process.

z/OS support of disk encryption is available on z/OS V1.10, or later.

Disable recovery key

On a DS8870, if you have a security administrator, you can configure or disable a recovery key for the DS8000 storage facility image before an encryption group is created. You can disable a recovery key within a secure key environment. The state of the recovery key must be unconfigured in order to disable the recovery key. Be aware that if you disable a recovery key, this allows an encryption group to be configured, but with no recovery alternative. If for some reason you do not want a recovery key, you should disable it.

Encryption deadlock recovery key supports the ability for administrators to restore access to a DS8870 when the encryption key for the storage is unavailable due to an encryption deadlock scenario. If clients disable the recovery key they do so at their own risk. Refer to the white paper IBM Encrypted Storage Overview V1.2 for best practices for prevention of the deadlock situation.

Rekey data keys of an encryption group

With security administrator access, users can rekey the data keys of their encryption group. With the encryption group rekey function, users can concurrently migrate a single platform key server configuration to a dual platform key server configuration to leverage changes in key management infrastructure. Both of these enhancements can help clients satisfy PCI security standards.

Solid state drives (SSD)

To improve data transfer rate (IOPS) and response time, IBM DS8000 series provides support for SSDs. SSDs support improved I/O transaction-based performance over traditional platter-based drives. IBM DS8870 will initially offer SSDs in 400 GB capacities with enhanced response time performance. SSDs are a high-IOPS class enterprise storage device targeted at Tier 0 applications that can use a high level of fast-access storage. SSDs offer a number of potential benefits over hard disk drives, including better IOPS performance, lower power consumption, less heat generation, and lower acoustical noise. The SSDs are optional to the DS8000 series and are available with feature numbers 6xxx.

SSDs will be limited to 384 drives per DS8870 system. Additionally, RAID-6 and RAID-10 are not supported for SSD arrays.

The DS8000 Point-in-Time Copy ( IBM FlashCopy ) function requires space to be set aside equal to the size of the volumes that are to be copied. The IBM System Storage DS8000 series provides support for IBM FlashCopy SE (space efficient snapshot capability) which is intended to use only the amount of storage needed by the copy. This capability can lower the amount of storage needed by many DS8000 clients today, and help lower costs by significantly reducing disk capacity needed for copies. Reducing capacity in the DS8000 can also mean fewer drives and less power required for the overall system.

IBM FlashCopy SE can be managed and configured via the DS Storage Manager, DS CLI, and DS Open API. All host systems supported by the DS8000 today are supported with FlashCopy SE ( IBM System z servers require z/OS 1.10, or later, for this support). For more information on implementation of this function, refer to the IBM System Storage DS8000 FlashCopy SE Implementation Considerations and Recommendations document located at

IBM FlashCopy SE is an optional feature on the DS8000 series, available with the SE indicator feature numbers 0730 and 735x-736x andcorresponding DS8000 series Function Authorization (2396-LFA SE featurenumbers 735x-736x).

Remote Pair FlashCopy

The IBM DS8870 provides Remote Pair FlashCopy with the capability to allow a FlashCopy (Point-in-Time Copy) relationship where the FlashCopy target device is a Metro Mirror primary device. This can significantly reduce the recovery time that exists when a FlashCopy background copy and Metro Mirror Resync are in progress. The Remote Pair FlashCopy provides a solution for data replication, data migration, remote copy, and disaster recovery tasks.

For business continuity, the Remote Pair FlashCopy operations are nondisruptive, allowing the primary device of each FlashCopy pair to remain available to all hosts for both read and write I/O operations. Once established, Remote Pair FlashCopy operations continue unattended to support continuous data backup to the secondary device.

z/OS support of Remote Pair FlashCopy is available on z/OS V1.10, or later, using the name FlashCopy Preserve Mirror.

Flexibility with support for RAID-5, RAID-6, and RAID-10

Physical capacity on the DS8000 series can be configured as RAID-5, RAID-6, RAID-10, or a combination of the three. RAID-5 can offer excellent performance for most applications, while RAID-10 can offer better performance for selected applications, in particular for high random write content applications in an open systems environment.

The decision to configure capacity as RAID-5, RAID-6, or RAID-10, as well as the amount of capacity to configure for each type, can be made at any time. RAID-5, RAID-6, and RAID-10 arrays can be intermixed within a single system and the physical capacity can be logically reconfigured at a later date (for example, RAID-6 arrays can be reconfigured into RAID-5 arrays).

Connectivity with Fibre Channel/FICON host adapters

The DS8000 series is designed to offer enhanced connectivity with the availability of four-port or eight-port Fibre Channel/FICON host adapters. The 8 Gb Fibre Channel/FICON host adapters, offered in longwave and shortwave, auto-negotiate to either 8 Gb, 4 Gb, or 2 Gb link speeds. This flexibility enables exploitation of the potential benefits offered by the higher performance, 8 Gb SAN-based solutions, while also maintaining compatibility with existing 2 Gb and 4 Gb infrastructures. In addition, the individual ports on the adapter can be configured with Fibre Channel Protocol (FCP) or FICON . This can help protect investment in Fibre Channel adapters and increase the ability to migrate to new servers. A DS8870 Model 961 can support up to a maximum of 16 host adapters, which equates to a maximum of 128 Fibre Channel ports.

DS8870 models offer extensive connectivity support, including Fibre Channel or FICON , across a broad range of server environments, such as IBM System z , System p , System i® , and System x® servers, as well as servers from Sun, Hewlett-Packard, and non-IBM Intel-based servers. This rich support of heterogeneous environments and attachments, along with the flexibility to easily partition the DS8000 series storage capacity among the attached environments, can help support storage consolidation requirements and dynamic, changing environments.

Improved performance with storage pool striping (rotate extents)

The storage pool striping (rotate extents) function, by default, stripes new volumes across all ranks of an extent pool to help reduce the administration required to balance system loads. With multiple rank allocation support, the system can automatically perform close to its highest efficiency, requiring little or no performance administration. The effectiveness of performance management is enhanced as imbalances tend to occur as isolated problems. The storage pool striping function can help automate hotspot avoidance for improved performance and response time without special tuning.

This function can be managed and configured via the DS Storage Manager, DS CLI, and DS Open API. All host systems supported by the DS8000 today are supported with storage pool striping. The storage pool striping function is provided with the DS8000 series at no additional charge.

Rich set of business continuance solutions

DS8870 models support a rich set of copy service functions and management tools that can be used to build solutions to help address business continuance requirements.

Point-in-time copy solutions

The FlashCopy advanced function is designed to provide a point-in-time copy capability for logical volumes. The FlashCopy function creates a physical point-in-time copy of the data, with minimal interruption to applications, and makes it possible to access both the source and target copies immediately.

FlashCopy supports many advanced capabilities, including:

Data Set FlashCopy - Allows a FlashCopy of a data set in a System z environment.

Multiple Relationship FlashCopy - Allows a source to have FlashCopy relationships with multiple targets simultaneously. This flexibility allows you to initiate up to twelve FlashCopy establishes on a given LUN, volume, or data set without needing to first wait for or cause a previous relationship to end.

Incremental FlashCopy - Provides the capability to refresh a LUN or volume involved in a FlashCopy relationship. When a subsequent FlashCopy Establish is initiated, only the data required to bring the target current to the source's newly established point-in-time is copied. The direction of the refresh can also be reversed, in which case the LUN or volume previously defined as the target becomes the source for the LUN or volume previously defined as the source (and now defined as the target).

Remote Mirror Primary FlashCopy - Allows a FlashCopy relationship to be established where the target is also a remote mirror primary volume. This enables a full or incremental point-in-time copy to be created at a local site, and then use remote mirroring commands to copy the data to the remote site.

Consistency Group Commands - Allows DS8870 model systems to hold off I/O activity to a LUN or volume until the FlashCopy Consistency Group command is issued. Consistency groups can be used to help create a consistent point-in-time copy across multiple LUNs or volumes, and even across multiple DS8870s.

Inband commands over remote mirror link - A remote mirror environment allows commands to manage FlashCopy at the remote site to be issued from the local or intermediate site and transmitted over the remote mirror Fibre Channel links. This helps eliminate the need for a network connection to the remote site solely for the management of FlashCopy. FlashCopy is an optional feature of the DS8870 models, and is available with the point-in-time indicator feature numbers 72xx and 0720 andcorresponding DS8000 series Function Authorization (2396-LFA featurenumber 72xx).

IBM FlashCopy SE price and efficiency options

The DS8000 Point-in-Time Copy ( IBM FlashCopy ) function requires space to be set aside equal to the size of the volumes that are to be copied. The IBM System Storage DS8000 series provides support for IBM FlashCopy SE (space efficient snapshot capability) which is intended to use only the amount of storage needed by the copy. This capability can lower the amount of storage needed by many DS8000 clients today, and help lower costs by significantly reducing disk capacity needed for copies. Reducing capacity in the DS8000 can also mean fewer drives and less power required for the overall system.

IBM FlashCopy SE can be managed and configured via the DS Storage Manager, DS CLI, and DS Open API. All host systems supported by the DS8000 today are supported with FlashCopy SE ( IBM System z servers require z/OS 1.10, or later, for this support). For more information on implementation of this function, please refer to the IBM System Storage DS8000 FlashCopy SE Implementation Considerations and Recommendations document located at

IBM FlashCopy SE is an optional feature on the DS8000 series, available with the SE indicator feature numbers 0730 and 735x-736x andcorresponding DS8000 series Function Authorization (2396-LFA SE featurenumbers 735x-736x).

Remote mirror and copy solutions

DS8870 models support several hardware-based remote mirror and copy solutions:

IBM System Storage Metro Mirror - This solution is designed to provide real-time mirroring of logical volumes between two systems that can be located up to 300 km from each other. It is a synchronous copy solution where write operations are completed on both copies (local and remote site) before they are considered to be done.

IBM System Storage Global Copy - This is a nonsynchronouslong-distance copy option for data migration and backup.

IBM System Storage Global Mirror - Global Mirror is a long-distance remote copy solution across two sites using asynchronous technology, and is designed to provide the following:

Support for virtually unlimited distance between the local and remote sites, with the distance typically limited only by the capabilities of the network and channel extension technology being used. This can better enable you to choose your remote site location based on business needs and enables site separation to add protection from localized disasters.

A consistent and restartable copy of the data at the remote site, created with little impact to applications at the local site.

Data currency where, for many environments, the remote site lags behind the local site as little as 3 to 5 seconds, helping to reduce the amount of data exposure in the event of an unplanned outage. The actual lag in data currency experienced will depend upon a number of factors, including specific workload characteristics and bandwidth between the local and remote sites.

Dynamic selection of the desired Recovery Point Objective (RPO) based upon business requirements and optimization of available bandwidth.

Session support whereby data consistency at the remote site is internally managed across up to eight systems located across the local and remote sites.

Efficient synchronization of the local and remote sites with support for failover and failback modes, helping to reduce the time required to switch back to the local site after a planned or unplanned outage.

Interoperability with existing and previous generations of DS8000 series

All of the above remote mirroring solutions use Fibre Channel as the communications link between the primary and secondary machines. The Fibre Channel ports used for remote mirror and copy can be configured as either a dedicated remote mirror link or as a shared port between remote mirroring and Fibre Channel Protocol (FCP) data traffic.

The remote mirror and copy solutions listed above are optional capabilities and are compatible with previous generations of DS8000 . They are available as follows:

DS8000 series systems can also participate in global copy solutions with the IBM TotalStorage ESS Model 750, IBM TotalStorage ESS Model 800, and IBM System Storage DS6000 series systems for data migration. For more information on data migration and migration services contact IBM or a Business Partner representative.

Global Copy is a nonsynchronous long-distance copy option for datamigration and backup, and is available under Metro Mirror and Global Mirror licenses or Remote Mirror and Copy license on older DS8000, ESS, or DS6000 systems.

Three-site Metro/Global Mirror

The DS8000 series supports three-site Metro/Global Mirror configurations. The Metro Mirror and Global Mirror functions utilize synchronous mirroring (Metro Mirror) from a local A-site to a metro-distance B-site, and asynchronous mirroring (Global Mirror) from an intermediate B-site to a remote C-site. This function, referred to as Metro/Global Mirror, is designed to provide planned and unplanned outage three-site enterprise disk data replication to help address rigorous three-site business resiliency needs of the enterprise data center. Metro/Global Mirror can support synchronous replication at distances up to 303 km using IBM System Storage Metro Mirror, and can maintain the asynchronous third site for out of region recovery, at a data currency that can be within 3 to 5 seconds (bandwidth permitting) using IBM System Storage Global Mirror.

Metro/Global Mirror is designed to provide:

Fast failover/failback to any site

Fast re-establishment of three-site recovery without production outages

Quick resynchronization to any site with incremental changes only

Metro/Global Mirror supports planned and unplanned switches from a local A-site to a remote B-site. With the cascading nature of Metro/Global Mirror, during and after the metro-distance switch, this function can provide continuous asynchronous disaster recovery protection to the out of region remote C-site without the necessity of additional reconfiguration. In the event of a loss of access to the B-site, Metro/Global Mirror is designed to provide incremental resynchronization from the local A-site to the remote C-site. The B-site can be brought back into the three-site configuration without a production outage, and with full failover and failback.

The Metro/Global Mirror solution uses Fibre Channel as the communications link between the primary, secondary, and tertiary machines. The Fibre Channel ports used for remote mirror and copy can be configured as either a dedicated remote mirror link or as a shared port between remote mirroring and FCP data traffic.

The Metro/Global Mirror solution is an optional capability of the DS8000 series and is available with the Metro/Global Mirror indicator feature numbers 74xx and 0742 and corresponding DS8000series Function Authorization (2396-LFA MGM feature numbers 74xx).

Quick initialization

IBM now supports quick initialization as an enhancement to device provisioning technology on DS8870 platforms. Quick initialization improves initialization speeds up to 2.6 times over previous versions and allows a copy services relationship to be established after a device is created, while the provisioning of storage is in progress. These improvements can help users to create an enterprise storage environment, quickly provision new logical devices, and move the devices into production while utilizing the new thin provisioning technology in less time than ever before on DS8000 systems.

Quick initialization is currently available on fixed block logical volumes and is also supported on CKD logical volumes.

IBM System Storage DS8870 Thin Provisioning

The DS8870 also offers thin provisioning to allow users to over-commit storage to specific devices and throughout the system in general. This has several potential benefits. First, users can now allocate larger logical devices without having to provision the entire device, allowing storage to be allocated on the DS8870 without repeated device resizing as would be required today. The level of over-commitment can be decided by the user, but as the system consumes physical storage, administrators will be notified of physical allocations as it reaches user-specified limits. Once all of the physical storage is in use, no further virtual storage can be allocated, so action must be taken before this condition occurs.

Thinly provisioned devices can be increased in size as needed if the logical size of the device becomes constrained. If the physical storage approaches full allocation within a given extent pool, then users can add additional physical capacity (via drive sets) to increase the size of the extent pool.

Users may see a reduction in operating costs by being able to deploy fewer physical disks to provision a given set of logical devices that are underutilized. Thin provisioned devices offer performance that is comparable to standard, fully allocated, logical devices, and are effective in reducing capacity allocations. The ability to overconfigure logical device capacities may also help to reduce operational costs related to expanding storage allocations for host system software components such as logical volume managers, file systems, and databases.

For the initial release, the IBM System Storage DS8000 thin provisioning feature is available only for open systems, excluding System i . Support for IBM System Storage DS8870 thin provisioning is an optional feature of the DS8870 Model 961, and is available with the thin provisioning licensed feature indicator feature numbers 7071 and 0707 and corresponding DS8870 Function Authorization (239x-LFA) Thin Provisioning feature number 7071.

Thin provisioning support for Copy Services function (open systems)

The FlashCopy advanced function is designed to provide a point-in-time copy capability for logical volumes. The FlashCopy function creates a physical point-in-time copy of the data, with minimal interruption to applications, and makes it possible to access both the source and target copies immediately.

Metro Mirror offers a synchronous, long-distance copy option that constantly updates a secondary copy of a volume to match changes made to a source volume. Global Mirror provides a long-distance remote copy solution across two sites using asynchronous technology. Metro Global Mirror is a three-site, high-availability disaster recovery solution, which uses synchronous replication to mirror data between a local site and an intermediate site, and asynchronous replication to mirror data from an intermediate site to a remote site.

The Copy Services function has extended the support of mixing thin provisioning volumes and logical volumes.

With this enhancement, existing customers that have thin provisioning volumes on the system and want to use the Copy Services function do not need any reconfiguration.

IBM System Storage Easy Tier®

IBM System Storage Easy Tier is designed to help automate data placement throughout the DS8870 disk pool (including multiple drive tiers) to intelligently align the system with current workload requirements. This includes the ability for the system to automatically and nondisruptively relocate data (at the extent level) across drive tiers, and the ability to manually relocate full volumes. The potential benefit is to align performance of the system with the appropriate application workloads.

Automated relocation - Manages volumes in an extent pool with SSD and HDD by automatically moving hot extents to SSD and cold extents to HDD.

Volume migration - Enables the manual relocation of volumes between extent pools, as well as the restriping of volumes within an extent pool, and the ability to merge existing extent pools.

Automated relocation

While SSDs can provide higher performance for most workloads, they do so at a significantly higher cost than traditional spinning drives. Even with recent improvements in the cost of SSDs, they remain an expensive option for many workloads, especially those requiring large amounts of storage. Based on those higher costs, it is often not realistic to replace all spinning drives with SSDs for a given application or workload. In order to improve performance of SSDs and reduce overall system cost, infrequently accessed (cold) data can and should reside on lower cost HDDs while frequently accessed (hot) data should be moved to the SSDs. The mix of SSDs and HDDs should be used to strike a proper balance between performance and cost.

IBM System Storage DS8870 introduces this capability with IBM System Storage Easy Tier . Easy Tier provides the ability to manage data placement between two tiers of storage, SSD and either Fibre Channel or SATA drives. Using a learning algorithm developed with the IBM Research organization, Easy Tier is designed to eliminate the complexity of manual data placement among tiers, while providing the value and flexibility of sub-volume or sub-LUN data placement. This supports improved performance cost options and is an improvement over traditional tiering methods that require manual intervention to move data between tiers, or ones that do not work at a granular level, requiring too much data to be moved to see any benefit. The IBM System Storage Easy Tier feature can determine the appropriate tier of storage based on data access requirements and then automatically move the data to the appropriate tier. This allows the manual effort involved to be reduced, if not eliminated. In this new dynamic environment, data movement is maintained to the host application regardless of the storage tier on which the data resides.

The IBM System Storage Easy Tier feature is designed to provide granularity in identifying and moving hot data at the sub-volume or sub-LUN (extent) level to SSDs. Easy Tier requires the use of a hybrid extent pool which contains both SSD and HDD drives. Sub-volume or sub-LUN (extent) from HDDs can be moved dynamically within a hybrid pool to SSD drives. Data movement done by the DS8870 is designed to be dynamic and transparent to the host server and application use of the data. The Easy Tier algorithm will assign heat values to each extent in a storage device. These heat values, hot or cold, will indicate what tier the data should reside on, and migration will take place automatically. Sub-volume or sub-LUN data movement is extremely important compared to full volume movement as not all data at the volume/LUN level will be hot data. Since for any given workload there is a distribution of data considered hot or cold , there is significant overhead associated with moving entire volumes between tiers. For example, if a volume is 1 TB, you would not have to move entire 1 TB volumes if the heat map generated indicates only 10 GB is considered hot . The DS8870 extent size is 1 GB, requiring only 10 extents to move to optimize the workload in this example, versus 1,000 extents for a less tuned method. This capability makes improved use of the SSD technology's higher performance while reducing the number of drives needed to improved that performance. In addition, depending on the workload and environment, it may be possible to combine Easy Tier , SSDs, and larger capacity drives and receive equivalent or better performance than traditional high-performance configurations (using small spinning disks) while providing smaller footprints and lower environmental costs.

Volume migration

Users can

Relocate logical volumes between extent pools or within an extent pool

Merge two extent pools with heterogeneous disks to use automated relocation

Change volume/rank to extent pool relationship without moving data

Volume migration implementation:

Offers transparent migration to attached hosts

Allows any supported volume to be queued for migration

Actively migrates a number of extents per CEC concurrently

Delivers overheads comparable to FlashCopy with background copy

The DS8870 has been enhanced to include performance monitoring capabilities, regardless of whether you have installed and activated the Easy Tier license feature on your DS8870. The monitoring capability of the DS8870 enables it to monitor the usage of storage at the volume extent level. Monitoring statistics are gathered and analyzed every 24 hours. In an Easy Tier managed extent pool, the analysis is used to form an extent relocation plan for the extent pool, which provides a recommendation for relocating extents on a volume to the most appropriate storage device. The results of this data is summarized in a summary report which you can download.

The DS8870 offers a reporting tool called IBM System Storage DS8870 Storage Tier Advisor, hereafter referred to as advisor tool. The advisor tool is a Microsoft Windows application that provides a graphical representation of performance data collected by the Easy Tier over a 24-hour operational cycle. Volume performance statistics are included in a summary binary file that is transformed to a readable statistical report that you can download to a directory you specify on your Windows workstation from which you are accessing the DS8870. The advisor tool is the application that allows you to view the data when you point your browser to the file. You can access the advisor tool with any supported web browser and view the information displayed by the advisor tool to analyze workload statistics and evaluate which logical volumes might be candidates for Easy Tier management. If you have not installed and enabled the Easy Tier feature, you can use the performance statistics gathered by the monitoring process to help you determine whether to use Easy Tier to enable potential performance improvements in your storage environment.

The value propositions of IBM System Storage Easy Tier are:

Manage storage performance within an enterprise storage system to improve dynamic application demand or dynamic system configuration

Improve performance costs by taking advantage of the spectrum of storage drives available

Improved throughput performance or a significant latency reduction can be achieved for the total workload with a small percentage of data relocation from tier 1 or 2 to tier 0

Moving small amounts of frequently accessed data to SSDs can result in a better response time or increased throughput, depending on customer workload and environment

Enables customers to develop new insights into application workloads on their storage infrastructure and develop new optimization strategies

Support for IBM System Storage Easy Tier is an optional feature of the DS8870 Model 961 and is available with the IBM System Storage Easy Tier licensed feature indicator feature numbers 7083 and 0713 and corresponding DS8870 Function Authorization (239x-LFA) IBM System Storage Easy Tier feature number 7083.

IBM System Storage Easy Tier enhancements

IBM delivers the second generation of IBM System Storage Easy Tier , designed to balance system resources to address application performance objectives by automating data placement across SSDs (tier 0), enterprise-class (tier 1), and nearline (tier 2) drives, as well as among the ranks of the same tier. This includes the ability for the system to automatically and nondisruptively relocate data (at the extent level) across drive tiers of storage and the ability to manually relocate full volumes. The benefit is to align performance of the system with the appropriate application workloads.

This enhancement can help to improve storage utilization and address performance requirements for multi-tier systems that are not yet deploying SSDs. Depending on the workload, up to 50% or more of tier one application data can be migrated to nearline (tier 2) without impacting application performance.

Effective automated tiering between enterprise-class and nearline drives can help reduce overall footprint and provide more cost-effective capacity, while addressing performance requirements.

The extended capabilities of Easy Tier version 2 are designed to support:

Cold demotion - Inactive cold data stored on a enterprise performance tier is demoted to a more appropriate tier.

Warm demotion - When a specific rank in the higher tier exceeds its optimal performance level, selected extents are moved to other ranks to eliminate the growing hotspot.

Auto-rebalance - Automatically relocates extents among the ranks within the tiers to remove workload skews on the ranks.

Automated relocation - Now supporting migration between any two classes of drives.

Volume migration - Enables the manual relocation of volumes between extent pools, the restriping of volumes within an extent pool, and the ability to merge existing extent pools into a single extent pool. Intra-pool restriping is now available to rebalance the volume across the available ranks, with a general bias toward providing pure striping, without requiring pre-allocation of all extents.

Cold demotion is designed to automatically recognize and demote inactive (cold) extents that are stored on a higher performance tier to an appropriate lower cost tier.

Cold demotion occurs when Easy Tier version 2 detects any of the following scenarios:

Segments in a storage pool become inactive over time, while other data remains active. This action can free up segments on the enterprise tier before the segments on the lower tier become hot , helping the system be more responsive to new data.

All the segments in a storage pool become inactive simultaneously due to either a planned or unplanned outage. In this situation, Easy Tier disables cold demote when storage pools are inactive between 15.5 and 24 hours. Disabling cold demote assists the user in scheduling extended outages or experiencing the outage without affecting the segment placement.

Warm demotion

The warm demote operation demotes hot extents in SSDs to HDDs, or from Enterprise FC to SATA drives to protect the drive performance on the system. In the enhanced Easy Tier version 2, warm demotion is rank-based and target rank is randomly selected from the lower tier. This function is triggered when bandwidth or IOPS thresholds are exceeded in the higher tier.

Auto-rebalance

In any tier, placing highly active (hot) data on the same physical rank can cause the drives or the associated device adapter (DA) to become a performance bottleneck. Over time, skews can appear within a single tier that cannot be addressed by migrating data to a faster tier alone, and requires some degree of workload rebalancing within the same tier. Auto-rebalance addresses these issues within a tier. It also helps the system respond in a more timely, appropriate manner to overloading skews and any under-utilization that might occur from the addition or deletion of hardware, migration of extents between tiers, changes in the underlying volume configurations, and variations in the workload. Auto-rebalance adjusts the system in order to continuously provide good performance by balancing the load on the ranks and on DA pairs.

Easy Tier enhancements provide extended and improved capabilities to support the automatic functions of auto-rebalance, warm demotion, and cold demotion, and will be made available on previous DS8700 Model 941, DS8800 Model 951, and the current DS8870 Model 961.

Rank depopulation

In the situation of drive technology upgrades, storage reconfigurations, and tearing down hybrid pools, rank depopulation allows users to relocate in-use extents away to the other ranks in the same pool and unassign the ranks from the pool. When ranks of a tier are depopulated from the hybrid pool, the pool is automatically treated as a traditionally managed pool, without dynamic optimization. After the depopulation, the ranks can be deleted or reconfigured to another pool.

IBM System Storage Easy Tier third generation

IBM System Storage Easy Tier third generation is designed to help automate data placement throughout the DS8000 disk pool between SSD drives (tier 1), enterprise class drives (tier 2), and nearline (tier 3) drives to intelligently align the system with current workload requirements. This includes the ability for the system to automatically and nondisruptively relocate data (at the extent level) across any three tiers of storage and within any tier. Relocation within tiers automatically rebalances workloads across available ranks, including ranks that are added to disk pools, to maximize the performance of each tier. Pools may be configured with one, two, or three tiers. The benefit is to align performance of the system with the appropriate application workloads. In addition, Easy Tier allows you to manually migrate logical volumes between extent pools, merge extent pools, or redistribute logical volumes across the available ranks within an unmanaged extent pool.

This enhancement can help clients improve storage utilization and address performance requirements for multitier systems that are not yet deploying SSDs. They can incrementally add SSDs to these traditional configurations for performance and nearline drives for cost savings depending on requirements. The DS8000 system performance can be automatically balanced across the new drives within the managed pool.

The extended capabilities of Easy Tier third generation support

Managed extent pools - Enables extended support for one tier and three tier environments, with management for provisioned volumes.

Volume migration - Enables the manual relocation of logical volumes between extent pools, restriping of logical volumes within an unmanaged extent pool, and the ability to merge existing extent pools. Easy Tier third generation has extended the support for thin provisioning volume migration and merging of extent pools that both contain thin provisioned volumes.

Auto-rebalance - Relocates extents among the ranks within a tier to remove workload skews on the ranks in a managed extent pool. Easy Tier third generation has extended the support for thin provisioning volumes and allows action on single tier and three tier pools to remove skews automatically, including cases where ranks are added to a managed extent pool.

Rank depopulation - Allows customers to nondisruptively relocate extents away from selected ranks and stop using the ranks. Easy Tier third generation has extended the support for thin provisioning volumes in addition to the standard volumes.

Remote mirror and copy solutions for z/OS

The following are three remote mirror and copy solutions for the z/OS environment for DS8870 models:

IBM System Storage z/OS Global Mirror: This is a combined hardware and software business continuance solution for the System z environment providing asynchronous mirroring between systems at two sites located global distances apart. z/OS Global Mirror is an optional capability of the DS8000 series and is available with the remote mirror for z/OS indicator feature numbers 76xx and 0760 and corresponding DS8000 series Function Authorization (2396-LFA RMZ feature numbers 76xx). z/OS Global Mirror also requires the purchase of the FICON attachment licensed feature.

z/OS Metro/Global Mirror (three-site z/OS Global Mirror and Metro Mirror): This mirroring capability utilizes z/OS Global Mirror to mirror primary site data to a location that is a long distance away and also uses Metro Mirror to mirror primary site data to a location within the metropolitan area. This enables a three-site, high availability and disaster recovery z/OS solution for even greater protection from unplanned outages. z/OS Metro/Global Mirror is an optional capability of the DS8000 series and is available with the remote mirror for z/OS indicator feature numbers 76xx and 0760 and corresponding DS8000 series Function Authorization (2396-LFA RMZ feature numbers 76xx) Mirror and Global Mirror features. z/OS Metro/Global Mirror also requires the purchase of a FICON attachment licensed feature.

Three-site z/OS Metro/Global Mirror Incremental Resync: This capability can eliminate the need for a full copy after a HyperSwap® situation in three-site z/OS Metro/Global Mirror configurations. The z/OS Metro/Global Mirror Incremental Resync capability is intended to enhance Remote Mirror for z/OS by enabling resynchronization of data between sites using only the changed data from the Metro Mirror target to the z/OS Global Mirror target after a GDPS® HyperSwap . This can significantly reduce the amount of data to be copied after a HyperSwap situation and improve the resilience of an overall three-site disaster recovery solution by reducing resync times. z/OS Metro/Global Mirror Incremental Resync is an optional feature of the DS8870 Model 961 and is available with the RMZ resync licensed feature indicator feature numbers 0763 and 76xx and DS8000 series Function Authorization (2396-LFA RMZ resync feature numbers 76xx). z/OS Metro/Global Mirror also requires the purchase of the FICON attachment licensed feature.

z/OS Distributed Data Backup

This provides the capability to perform reliable backup of open systems data from distributed server platforms via a System z host. The open systems data will be transferred to the System z host via the fixed block command set used for the 3880 control unit, allowing backup of open data on distributed servers that are not formatted for mainframe System z I/O commands. Currently, clients are not able to effectively use System z I/O commands to backup open data along with their mainframe data. This will provide a multi-platform backup capability from System z .

The Innovation Data Processing application will issue commands from z/OS to read/write data to LUNs. Support for IBM z/OS Distributed Data Backup is an optional feature of the DS8870 Model 961. It is available with the z/OS Distributed Data Backup licensed feature indicator, feature numbers7094 and 0714, and corresponding DS8870 Function Authorization (239x-LFA)z/OS Distributed Data Backup feature number 7094.

IBM performance innovations for System z environments

FICON extends the ability of the DS8000 series system to help deliver high bandwidth potential to the logical volumes needing it, when they need it. Older technologies are limited by the bandwidth of a single disk drive, but FICON, working together with other DS8000 series functions, provides a high-speed pipe supporting multiplexed operation.

Support for FICON attachment is an optional feature of DS8870 Model 961 and is available with the FICON attachment licensed feature indicator feature numbers 7091 and 0703 and corresponding DS8000 seriesFunction Authorization (2396-LFA FICON attachment feature number 7091).

Parallel Access Volumes (PAV) enable a single System z server to simultaneously process multiple I/O operations to the same logical volume to significantly reduce device queue delays by defining multiple addresses per volume. With Dynamic PAV, the assignment of addresses to volumes can be automatically managed to help meet performance objectives and reduce overall queuing. PAV is an optional feature on the DS8000 series and is available with the PAV indicator feature numbers 78xx and0780 and corresponding DS8000 series Function Authorization (2396-LFAPAV feature numbers 78xx). PAV also requires the purchase of the FICON attachment licensed feature.

HyperPAV allows an alias address to be used to access any base on the same control unit image per I/O base. This capability also allows different HyperPAV hosts to use one alias to access different bases, reducing the number of alias addresses required to support a set of bases in a System z environment with no latency in targeting an alias to a base. This functionality is designed to enable applications to achieve equal or better performance than possible with the original PAV feature alone while using the same or fewer z/OS resources.

HyperPAV is an optional feature on the DS8000 series and is available with the HyperPAV indicator feature numbers 7899 and 0782 andcorresponding DS8000 series Function Authorization (2396-LFA HyperPAVfeature number 7899). HyperPAV also requires the purchase of PAV licensed features and the FICON attachment licensed feature.

Performance improvements to High Performance FICON for System z (zHPF) for:

QSAM, BPAM, and BSAM access methods: With zHPF with z/OS V1.13, zEnterprise servers and IBM System Storage has been designed to deliver significant I/O performance improvements for certain I/O transfers for workloads using QSAM, BPAM, and BSAM access methods. Significant I/O performance improvements are expected without the need for application changes. This builds upon existing zHPF support for VSAM, Extended Format sequential, zFS, and PDSE data sets, and provides support for these data set types when a new parameter is specified in the IGDSMSxx member of parmlib:

Basic nonextended format physical sequential data sets

Basic and large format sequential data sets

The zHPF function without the most recent enhancements is supported on DS8000 series systems running on IBM zEnterprise servers with all supported FICON features (CHPID type FC) and z/OS V1.11, or later.

Format writes: zHPF has also been enhanced to support format writes. This capability applies to all of the same data set types that were originally supported by the Modified Indirect Data Address Word (MIDAW) facility and zHPF, in addition to QSAM, BPAM, and BSAM data sets described above. The performance value of these enhancements are highest for small records, which are typically used for databases.

DB2 utilities use format writes. Those utilities that load or restore data into a table space or index with a 4K page size are expected to experience the most benefit.

The zHPF enhancement for format writes is supported on the DS8000 series systems running on IBM zEnterprise servers with all supported FICON features (CHPID type FC) and z/OS V1.11, or later.

DB2 List Prefetch: zHPF has also been enhanced to provide improvements for DB2 List Prefetch processing when using 4K pages. zHPF list prefetch is supported by the FICON Express4 and FICON Express8 features. However, those features limit the number of discontinuities that a single zHPF channel program can have to 22. If the number exceeds 22, z/OS splits the pages into two I/Os. This applies to 4K pages, since DB2 for z/OS typically reads 32x4K pages. The FICON Express 8S features remove this limitation. The result is fewer I/Os than when using FICON Express4 or FICON Express features.

The function is supported on DS8000 series systems running on IBM zEnterprise servers with FICON Express8S features (CHPID type FC) and z/OS V1.11, or later.

HyperSwap ( GDPS ) support

HyperSwap support is designed to enhance and improve recovery in HyperSwap-enabled configurations. This support is intended to mitigate the impact of recovery scenarios and is targeted for GDPS/PPRC IBM System Storage DS8700, DS8800, or later series clients.

The DS8000 implements a new event reporting mechanism for events that greatly reduce the impact on host operating systems. This support is targeted to GDPS and PPRC clients with DS8000 disk and is intended to mitigate the impact of various, primary PPRC DS8000 recovery scenarios on host processing. The DS8000 will notify GDPS and PPRC of any recovery processing that will impact host I/Os for an extended period. GDPS and PPRC, based upon the DS8000 notification, will initiate an unplanned hot swap.

The function is supported on DS8000 series systems running on IBM System z servers with z/OS V1.13, or later, and GDPS V3.8, or later.

IBM Extended Address Volumes (EAV) for System z environments

The EAV function provides support for volumes that can scale up to approximately 1 TB (1,182,006 cylinders), helping to relieve address constraints to support large storage capacity needs in System z environments. Larger devices can help simplify storage management by managing fewer large volumes as opposed to many small volumes. The HyperPAV function complements EAV by allowing scaling of I/O rates against a single, larger volume. Dynamic Volume Expansion allows nondisruptive migration to the larger volume sizes now available. The function is supported on DS8000 series systems running on IBM System z servers with z/OS V1.10, or later. The EAV capability is provided with the DS8000 series at no additional charge.

Multiple allegiance expands the simultaneous logical volume access capability across multiple System z servers. This function, along with PAV, enables the DS8000 series to process more I/Os in parallel, helping to improve performance and enable greater use of large volumes.

Previously, FICON working together with other DS8000 series functions provided a high-speed connection supporting multiplexed operation. High Performance FICON takes advantage of the hardware available today with enhancements that are designed to reduce the overhead associated with supported commands. Enhancements have been made to the z/Architecture® and the FICON interface architecture to deliver improvements for online transaction processing workloads. zHPF is designed to help reduce overhead and improve performance when exploited by the FICON channel, the z/OS operating system, and the control unit. Additionally, the changes to the architectures offer end-to-end system enhancements to improve reliability, availability, and serviceability. Existing adapters will be able to handle an intermix of transactions using FCP, FICON , and High Performance FICON protocols.

High Performance FICON can support more than one track's worth of data in a single transfer. Applications using Media Manager for I/O with large data transfers are expected to benefit those using zFS, HFS, PDSE, and striped extended format data sets. This function is available on z/OS V1.9 and z/OS V1.10 with the PTFs for APARs OA26084 and OA29017.

This function is a modification to the FICON I/O architecture and is being worked on for inclusion into the Fibre Channel Standard by the INCITS Fibre Channel (T11) Technical Committee's FC-SB-4 project.

Support for High Performance FICON multi-track is an optional feature of DS8870 Model 961 and is available with the High Performance FICON licensed feature indicator feature numbers 7092 and 0709 andcorresponding DS8000 series Function Authorization (2396-LFA HighPerformance FICON feature number 7092).

z/HPF extended distance

Reduces the impact associated with supported commands on current adapter hardware, thereby improving FICON throughput on the DS8870 I/O ports.

I/O priority queuing

I/O priority queuing allows the DS8000 series to use I/O priority information provided by the z/OS Workload Manager to manage the processing sequence of I/O operations.

DS8000 I/O Priority Manager

The DS8000 now features I/O Priority Manager which enables more effective storage consolidation and performance management with the ability to align quality of service levels to separate workloads in the system. This capability is exclusive to the DS8000 and System z systems.

Users define performance goals based on priority of high, medium, or low to any volume and the system will prioritize access to system resources to achieve the volume's desired quality of service. I/O Priority Manager is designed to constantly monitor and balance system resources to help applications meet their performance targets automatically, without operator intervention.

This release also provides enhanced data protection for multitenancy environments that use copy services. With Copy Services Scope Management, copy service relationships can be limited to the domain of a set of user specified resources. Additionally, user IDs can be configured to limit a given user ID to issuing copy services requests to a specific domain. This capability allows specific resources to be managed for copy services by a specific user and prevents any host or user from initiating a copy services operation that would cross any domain boundaries. The Copy Services Scope Management capability is available for any host type on any volume type (CKD or FB). In addition to this multitenant capability, copy services domains can also provide general purpose partitioning to isolate heterogeneous environments from each other.

DS8000 Storage Manager GUI

An updated GUI now enables easier, more effective management of the system and its advanced features. The enhanced design was inspired by the IBM System Storage XIV® GUI and includes more intuitive navigation panels and streamlined configuration processes, as well as embedded links to relevant videos for quick access to useful DS8000 information. These changes were based on newer GUI technology and the common UI elements across the storage portfolio. This common GUI supports DS8000 , Storwize® V7000, and SAN Volume Controller (SVC) by having a common look and feel, as well as common terminology and icons to greatly simplify management of the various systems that use this common GUI, and significantly reduce the costs associated with administrator training.

GUI support for resource groups

An updated GUI now enables easier, more effective management of the resource groups configurations. This DS8000 GUI allows users to create, modify, and delete Logical Volume and Logical Subsystems (CKD/FB), and display the resource group attribute.

This GUI can greatly simplify configurations and management of the resource groups that use this GUI and significantly reduce the costs associated with administrator training.

DS8000 Storage Manager enhancement

Enhancements were added to the DS Storage Manager (GUI) for the DS8870 for easier and more efficient storage management. The DS Storage Manager is installed as a GUI for the Windows and Linux operating systems. In addition to using IBM Tivoli Storage Productivity Center, the GUI can be accessed from any location that has network access using a web browser.

Supported browsers include:

Microsoft Internet Explorer 8 or 9

Mozilla Firefox 10 ESR

Security enhancements

Users logging onto the DS8000 storage system have to be compliant to ITSC104 password requirements. Storage administrators have the ability to determine which users are currently logged into the DS8000 and disconnect users who may no longer be authorized to access the DS8000 with their current authorization roles or resource scopes.

IPV6 support

The DS8000 has been qualified as meeting the requirements of the IPv6 Ready Logo program, indicating its implementation of IPv6 mandatory core protocols and the ability to interoperate with other IPv6 implementations. DS8000 systems can be configured in native IPv6 environments.

Licensing capabilities for copy functions

With DS8870 models, licensing options are available for users of FlashCopy (point-in-time copy indicator feature), Metro Mirror, and Global Mirror indicator features as follows:

If the function is used with open systems data only, a license is required for only the total physical capacity configured as fixed block (FB).

If the function will be used with System z data only, a license is required for only the total physical capacity configured as count key data (CKD).

If the function is used with both open systems and System z data, a license is required for the total physical capacity of DS8000 series system.

In addition, the license scope (FB, CKD, or entire machine) client is managed through an IBM web-based application to change the license scope on a given machine as business requirements change.

Additional DS8000 functions

End-to-end I/O priorities: The DS8000 series host adapter allows preferential treatment to higher priority I/O and provides improved response time in the overall system operation while running in IBM System p AIX® and DB2® operating environments.

Cooperative caching: The storage facility uses a cache hint to manage the retention period of cached data and provides improved overall system performance through more efficient use of the aggregate memory resources while running in IBM System p AIX and DB2 operating environments.

Intelligent write caching: Write caches using fast, nonvolatile storage are now widely used in modern storage controllers since they help reduce latency on writes. Intelligent write caching utilizes a newly developed algorithm for write management to boost performance through improving utilization of both temporal locality (data most recently modified) and spatial locality (data located physically together). To increase aggregate throughput and reduce aggregate response times, the IBM DS8000 series now provides enterprise storage controllers utilizing the intelligent write caching algorithm.

Long busy wait host tolerance: Host tolerance delivers a new protocol that allows a target to specify that it is busy and how long the initiator should wait before retrying. This avoids initiator failure of I/O after numerous retries and receiving busy responses, and avoids the initiator retrying too soon while running in the IBM System p AIX operating environments.

Audit logging: DS8000 supports audit logging and viewing of an exported log file. The DS8000 audit logging capability includes information such as a list of users who have logged in and what the user did during their session. A separate log entry is added each time a resource is created, deleted, or modified providing enhanced administrator ease-of-use and additional security.

Concurrent code load improvements

The current DS8870 code load process combines multiple phases of code load into one step. Because of this, code loads are perceived to be unnecessarily long. Splitting the phases into two allows for one phase (distribution) to be done ahead of time without any loss of access or quiescing of any resource (no loss of redundancy). This would leave the other phase (activation) to be much shorter and could be scheduled during off-peak periods. This will allow for a less than 2-hour activation phase of the main components of the DS8870. Once installed, this capability will be enabled when moving forward to future levels of code.

Prevent deletion of CKD and FB volumes in use

The DS8870 supports additional measures to prevent online devices from deletion. Online devices have a specific meaning based on volume type. For CKD volumes, the volume is online if it is participating in any Copy Services relationship, or if it is grouped dynamic-pathing state . FB volumes are online if they are in a Copy Services relationship. The DSCLI will now always check for online status before completing a deletion command.

Smart Rebuild is designed to help reduce the possibility of secondary failures and data loss in RAID Arrays. The array rebuild process has been designed to read data from as few drives in the array as possible. This can help reduce the amount of time required to rebuild the data in the array, as well reducing the exposure to a second drive failure during the rebuild process.

The above functions are provided with the DS8000 series at no additional charge.

Management tools and utilities for administrator productivity

The DS8000 series models support the following management tools and utilities:

IBM System Storage management console: The management console is the focal point for maintenance activities and is a dedicated laptop that is physically located (installed) inside your DS8870 and can proactively monitor the state of your system, notifying you and IBM when service is required. It can also be connected to your network to enable centralized management of your system using the IBM System Storage DS® Command Line Interface or storage management software utilizing the IBM System Storage DS Open API. An external Management Console is available as a optional feature and can be used as a redundant management console for environments with high availability requirements.

IBM Tivoli Storage Productivity Center: IBM Tivoli Storage Productivity Center is a storage resource management application available for DS8000 management. It is designed to provide centralized, automated, and simplified management of complex and heterogeneous storage environments.

IBM Tivoli Storage Productivity Center 5.1 provides a wealth of storage resource management tools. It extends existing management of a single storage system, providing capabilities such as storage reporting, monitoring, and policy-based management. Additionally, it provides storage device configuration, performance monitoring, and management of storage area network (SAN) attached devices. It provides over 400 enterprise-wide reports, monitoring alerts, policy-based action, and file-system capacity utilization information in a heterogeneous environment. IBM Tivoli Storage Productivity Center is designed to help improve capacity utilization of storage systems, adding intelligence to data protection and retention practices. IBM Tivoli Storage Productivity Center 5.1 now includes replication management capabilities designed to support hundreds of replication sessions across thousands of data volumes and supports both open and z/OS-attached volumes.

IBM Tivoli Storage Productivity Center for replication for System z offers the same capabilities and support that are provided by the IBM Tivoli Storage Productivity Center for Replication, but for the System z environment. It supports:

IBM System Storage DS command line interface (CLI) is a single CLI that has the ability to perform a wide range of commands for both configuration and copy services activities. The application has three modes of execution:

Single shot mode will connect, issue a single command, and then return to the user.

Script mode will connect, execute a predefined customer script, and then return to the user.

Interactive mode will place the user in a shell environment with a static connection to the storage subsystem so the user can execute multiple commands.

The CLI has the ability to dynamically invoke copy services functions. This can help enhance your productivity since it eliminates the previous requirement for you to create and save a task using the GUI. The DS CLI can also issue copy services commands to an ESS Model 750, ESS Model 800, or DS6000 series system. The DS CLI is available with the DS8870 models at no additional charge. The DS CLI client is available for the AIX , HP-UX, Linux , Novell NetWare, Sun Solaris, and Microsoft Windows operating system environments.

IBM System Storage DS open API supports routine LUN management activities, such as LUN creation, mapping and masking, and the management of point-in-time copy and remote mirroring. It supports these activities through the use of a standard interface as defined by the Storage Networking Industry Association (SNIA) Storage Management Initiative Specification (SMI-S). DS Open API is implemented through the IBM System Storage Common Information Model Agent (CIM Agent) for the DS Open API, a middleware application designed to provide a CIM-compliant interface. The interface is designed to allow Tivoli and third-party CIM-compliant software management tools to discover, monitor, and control DS8000 series systems. The DS Open API and CIM Agent are provided with the DS8870 models at no additional charge.

IBM System Storage multi-path subsystem device driver (SDD) is designed to provide load balancing and enhanced data availability capability in configurations with more than one I/O path between the host server and the DS8000 series system. Load balancing can help reduce or eliminate I/O bottlenecks that occur when many I/O operations are directed to common devices via the same I/O path. SDD also helps eliminate a potential single point of failure by automatically rerouting I/O operations when a path failure occurs, thereby supporting enhanced data availability capability. SDD is provided with the DS8870 models at no additional charge.

The deactivation of an activated licensed function, or a lateral change or reduction in the license scope, is a nondisruptive activity which will occur at the next machine IML.

A lateral change is defined as changing the license scope from FB to CKD or from CKD to FB.

A reduction is defined as changing the license scope from ALL to FB or from ALL to CKD.

The amount of physical capacity within a 2421 system that can be logically configured for use will be enforced by the 2421 Licensed Machine Code to maintain compliance with the extent of IBM authorization established for licensed functions activated on the machine.

SSD limitations

SSD drive sets are not supported in RAID-6 or RAID-10 configurations. Intermixing of drives within the disk enclosure is not supported on the entire system.

Thin provisioning limitations

No thin provisioning support on System z/OS volumes series.

Model conversion/upgrade limitations

No brand model conversion from 951/95E to 961/96E

Business class configuration reduces the total number of drives per system to 144. This restriction can be removed by concurrently upgrading to other processor/memory combinations.

Planning information

Customer responsibilities

Physical configuration planning

Physical configuration planning is a customer responsibility. A marketing specialist can help plan and select the DS8000 series physical configuration and features. Introductory information, including required and optional features, can be found in the IBM System Storage DS8870 Introduction and Planning Guide (GC27-4209).

Capacity and performance planning assistance is also available. Through the use of Disk Magic, a disk marketing specialist can help plan and anticipate performance characteristics for specific workloads by modeling proposed configurations.

Installation planning

Installation planning is a customer responsibility. Information about planning the installation of a DS8000 series, including equipment, site, and power requirements, can be found in the IBM System Storage DS8870 Introduction and Planning Guide (GC27-4209).

Logical configuration planning and application

Logical configuration planning is a customer responsibility. Logical configuration refers to the creation of RAID ranks, volumes, and LUNs, and the assignment of the configured capacity to servers.

Application of the initial logical configuration and all subsequent modifications to the logical configuration is a customer responsibility. The logical configuration can be created, applied, and modified using the DS Storage Manager, DS CLI, or DS Open API.

IBM may release changes to the DS8000 series Licensed Machine Code. IBM plans to make most DS8000 series Licensed Machine Code changes available for download by the DS8000 series system from the IBM System Storage technical support website. Not all Licensed Machine Code changes may be available via the support website. If the machine does not function as warranted and a problem can be resolved through the application of downloadable Licensed Machine Code, the customer is responsible for downloading and installing these designated Licensed Machine Code changes as IBM specifies. IBM has responsibility for installing changes that IBM does not make available for you to download. The DS8000 series includes many enhancements to make the Licensed Machine Code change process simpler, quicker, and more automated. A request can be made for IBM to install downloadable Licensed Machine Code changes, however there may be a charge for that service.

Calculating physical and effective capacity

Refer to the IBM System Storage DS8870 Introduction and Planning Guide (GC27-4209) for capacity calculation guidelines.

Encryption planning

Encryption planning is a customer responsibility. here are three major planning components to the implementation of an encryption environment. Review all planning requirements and include them in the installation considerations.

Key server planning

Tivoli Key Lifecycle Manager (TKLM) planning

Full Disk Encryption Activation review planning

Key server planning

Key server planning is a customer responsibility. Introductory information, including required and optional features, can be found in the IBM System Storage DS8870 Introduction and Planning Guide (GC27-4209).

DS8870 requires at least two key servers and associated software for each site which has one or more encryption-enabled DS8000 systems, according to the encryption best practices. One server must be isolated and the others can be of any supported key server configuration. Any site that operates independently of other sites must have key servers for the encryption enabled DS8000 systems at that site.

DS8000 Encryption environments are recommended to configure external Laptop HMC for high availability (feature number 1130).

It is the customer's responsibility to replicate any key labels and their associated key material across all key servers attached to a given encryption-enabled DS8000 before configuring that key label on the DS8000 .

Dual platform key server planning

DS8000 supports the ability to configure two independent key labels for each encryption-enabled DS8000 . This capability allows the use of two independent key server platforms when one or both key server platforms are using secure-key mode key stores, allowing the isolated key server platform to be used in conjunction with a second key server platform that is operating with a secure-key mode key store.

For customers needing dual platform key server support on DS8000 , the installation of TKLM IFIX 2 (TKLM Version 1.0.0.2, or later) is recommended to support displaying both key labels in the GUI. Additionally, for customers who intend to replicate keys between separate z Series Sysplexes using ICSF with the JCECCARACFKS key store in secure key mode and with the secure key configuration flag set in TKLM, TKLM Fix Pack 3 (TKLM Version 1.0.0.3, or later) is required.

Isolated key servers ordered with feature number 1760 will have a Linux operating system and TKLM software preinstalled.

Customer acquired Isolated Key Server

Refer to the IBM Tivoli Key Lifecycle Manager Installation and Configuration Guide (SC27-2741) for hardware and operating system requirements.

Note: Regardless of the ordering method, customers will need to acquire a TKLM license for use of the TKLM software ordered separately from the stand-alone server hardware.
Note: The licensing for TKLM includes both an install license for the TKLM management software as well as licensing for the encrypting drives.

Full Disk Encryption Activation is a customer responsibility. IBM Full Disk Encryption offerings must be activated prior to use. This activation is part of the installation and configuration steps required for use of the technology. This installation and activation review is performed by the IBM Systems and Technology Lab Services group.
